Notwithstanding anything herein to the contrary, if there are material sales of Licensed Products by Gilead, its Affiliates or Sublicensees to unaffiliated Third Parties at a price in excess of the Affordable Basis in a country or territory in the Access Territory, the Parties shall determine a mechanism to include the amounts invoiced for such sales within Net Sales hereunder.

If a Licensed Product is sold or otherwise commercially disposed of for consideration other than cash or in a transaction that is not at arm’s length between the buyer and the seller, then the gross amount to be included in the calculation of Net Sales shall be the amount that would have been invoiced had the transaction been conducted at arm’s length and for cash. Such amount that would have been invoiced shall be determined, wherever possible, by reference to the average selling price of the relevant Licensed Product in arm’s length transactions in the relevant country.

version of this exhibit has been filed separately with the Commission.

such country, but the Licensed Product component of the Combination Product is sold separately in such country, Net Sales for the purpose of determining royalties due hereunder for the Combination Product will be calculated by multiplying the actual Net Sales of such Combination Product by the fraction A/C, where A is the total weighted (by sales volume) average Net Sales price of such Licensed Product component if sold separately, and C is the total weighted (by sales volume) average Net Sales price of the Combination Product. If, on a country-by-country basis, such Licensed Product component is not sold separately in such country, Net Sales for the purposes of determining royalties due hereunder for the Combination Product will be calculated by multiplying the actual Net Sales of such Combination Product by the fraction D/(D+E), where D is the worldwide average Net Sales price of the portion of the Combination Product that contains the Licensed Product, and E is the worldwide average Net Sales price of the portion of the Combination Product containing the other active ingredients included in such Combination Product.

If Development of the first Program DART or Licensed Product from a Licensed Program has been discontinued, then the achievement by a subsequent Program DART or Licensed Product from such Licensed Program of a milestone event not achieved by such substituted or discontinued first Licensed Product shall be deemed to be achievement of the corresponding milestone event under Section 8.3.1 by the first Licensed Product entitling MacroGenics to the corresponding milestone payment under Section 8.3.1 Column I. By way of example, if a first and second Licensed Product from a given Licensed Program have been Developed concurrently and the Development of such first Licensed Product is discontinued, such second Licensed Product shall be eligible for any milestone events under Section 8.3.1 Column I not previously achieved by such first Licensed Product and, conversely, any milestone events under Section 8.3.1 Column I achieved by such first Licensed Product shall not be payable with respect to such second Licensed Product. Further, any third Licensed Product from such Licensed Program that contains a Program DART other than the Program DART contained in the second Licensed Product shall be eligible for any milestone events under Section 8.3.1 Column II not previously achieved by such second Licensed Product.

8.3.4 Notification; Payment. Gilead shall promptly notify MacroGenics in writing of the first achievement of each of the milestones under this Section 8.3 and the corresponding milestone payment shall be due within *** after receipt of the corresponding invoice from MacroGenics.

8.4 Sales Milestones.

8.4.1 Sales Milestone Payments. During the License Term for each Licensed Program, Gilead shall make the non-refundable, non-creditable payments to MacroGenics set forth below upon the earliest achievement of each of the corresponding milestone events by the first Licensed Product from such Licensed Program to achieve such milestone:


Milestone Event		Payment

(a) First occurrence of Annual Net Sales of a Licensed Product greater than * Dollars (*) in a Calendar Year		***

(b) First occurrence of Annual Net Sales of a Licensed Product greater than * Dollars (*) in a Calendar Year		***

(c) First occurrence of Annual Net Sales of a Licensed Product greater than * Dollars (*) in a Calendar Year		***

(d) First occurrence of Annual Net Sales of a Licensed Product greater than * Dollars (*) in a Calendar Year		***

8.4.2 Payment of Sales Milestones. Gilead shall make the milestone payments required by Section 8.4.1 in accordance with Section 8.7. If an event described in a clause in Section 8.4.1 occurs during the same Calendar Quarter as another event described in a preceding clause in Section 8.4.1, Gilead shall also pay the milestone payment described in such earlier clause when the milestone payment described in such later clause is paid. By way of example, if, during any Calendar Quarter, Annual Net Sales for a Licensed Product from a given Licensed Program first exceed the thresholds set forth in Sections 8.4.1(a) and (b), Gilead shall pay MacroGenics the milestone payments set forth in both Sections 8.4.1(a) and (b).

8.5 Royalties.

8.5.1 Annual Net Sales. Subject to Section 8.5.4(c), for each Licensed Product in each Calendar Year during the Royalty Term, Gilead shall pay MacroGenics royalties on Annual Net Sales of such Licensed Product in the Gilead Territory in such Calendar Year at the following rates:


Annual Net Sales Threshold		Royalty Rate

(a) On the first * Dollars (*) in Annual Net Sales of such Licensed Product in such Calendar Year		***

(b) On that portion of Annual Net Sales of such Licensed Product in such Calendar Year greater than * Dollars () but less than or equal to (*)		***

(c) On that portion of Annual Net Sales of such Licensed Product in such Calendar Year greater than * Dollars (*)		***

8.5.2 Net Receipts. Gilead shall pay MacroGenics twenty percent (20%) of all Net Receipts in accordance with Section 8.7.

8.5.3 Diagnostics. If (a) Gilead or any of its Affiliates or Sublicensees Commercializes in any country a Diagnostic and (b) Gilead or its Affiliates receive sales, royalty revenues or other consideration from such Commercialization, the Parties shall negotiate in good faith a reasonable royalty to be paid by Gilead to MacroGenics with respect to such revenues, taking into consideration Gilead’s profit component, which royalty shall be consistent with industry standards for diagnostics but in any case shall not exceed the rates set forth in Section 8.5.1. Notwithstanding anything in this Agreement to the contrary, if the Parties are unable to agree upon the royalty rate after exhausting the procedures set forth in Section 15.1, ***.

8.5.4 Royalty Term.

(a) Gilead’s royalty obligations to MacroGenics under this Section 8.5 with respect to any Licensed Product in any country shall commence upon the First Commercial Sale of such Licensed Product in such country and expire on a country-by-country basis on the later of: (i) the expiration of the last to expire Valid Claim within the MacroGenics Patents and/or Joint Patents that Cover such Licensed Product in such country; (ii) the twelfth (12th) anniversary of the date of the First Commercial Sale of such Licensed Product in such country; and (iii) the expiration of the last-to-expire applicable Regulatory-Based Exclusivity Period for such Licensed Product in such country (the “Royalty Term”). For avoidance of doubt, all Regulatory-Based Exclusivity Periods for a Licensed Product in a country shall be deemed to have expired upon the launch in such country of a Biosimilar Product.

*** = Portions of this exhibit have been omitted pursuant to a request for confidential treatment. An unredacted

version of this exhibit has been filed separately with the Commission.

(b) Royalties shall be payable only once with respect to the same unit of Licensed Product. On a Licensed Product-by-Licensed Product and country-by-country basis, upon expiration of the Royalty Term for a Licensed Product in a country in the Gilead Territory, Gilead’s licenses and rights hereunder with respect to such Licensed Product in such country shall continue in effect, but become fully paid-up, royalty-free, transferable (to the extent not transferrable previously), perpetual and irrevocable.

(c) For any Calendar Quarter of the Royalty Term during which a Licensed Product is sold in a country in which one (1) or more Third Parties sell in such country one or more Biosimilar Products, and such Biosimilar Products, collectively, have a *** or more market share of the aggregate market share of such Licensed Product and such Biosimilar Products (based on data provided by IMS Health Incorporated, Fairfield, Connecticut) as measured on a units sold basis, or if such data is not available, the Parties shall agree upon a methodology for estimating the percentage of unit sales based market share of such Biosimilar Products in such country), then, Gilead’s royalty obligations with respect to sales of such Licensed Product in such country during such Calendar Quarter shall be reduced by *** of the applicable rate set forth in Section 8.5.1. The Parties shall mutually agree in good faith on an appropriate method of calculating the royalties payable by Gilead pursuant to this Section 8.5 in the event such circumstances arise. “Biosimilar Product” means, with respect to a Licensed Product sold in a country, a product that: (i) is marketed by a Third Party that has not obtained the rights to such product as a Sublicensee or distributor of, or through any other contractual relationship with, Gilead or any of its Affiliates; (ii) contains the same or highly similar active ingredient(s) as the applicable Licensed Product; and (iii) with respect to (x) the United States, has been licensed as a biosimilar or interchangeable biological product by FDA pursuant to Section 351(k) of the Public Health Service Act (42 U.S.C. § 262(k)), as may be amended, or any subsequent or superseding law, statute or regulation, (y) the EU, has been approved in reliance on the prior approval of a Licensed Product as a similar biological medicinal product by the European Union pursuant to Directive 2001/83/EC, as may be amended, or any subsequent or superseding law, statute or regulation, and (z) any other country, has received analogous regulatory marketing approval in reliance on the prior approval of a Licensed Product from the applicable Regulatory Authority

8.5.5 Third Party Offset. If, after the License Grant Date for any Licensed Program, Gilead or its applicable Affiliate or Sublicensee: (a) is required, as reasonably determined by Gilead or its applicable Affiliate or Sublicensee, as the case may be, to obtain a license from any Third Party under any Patents controlled by such Third Party in order to make, have made, use, sell, offer for sale or import a Program DART and/or a Licensed Product from such Licensed Program in any country in the Gilead Territory without infringing such Patents, and pursuant to such license is required to pay any amounts to such Third Party (including any upfront, milestone or royalty payments) in any Calendar Year, or (b) is required by any court of competent jurisdiction, in connection with its infringement of any Patents controlled by a Third Party in any country in the Gilead Territory with respect to a Program DART and/or Licensed Product from such Licensed Program, to pay any amounts to such Third Party (including any

lump sum or royalty payments) in any Calendar Year, then Gilead may deduct from the milestone payments and/or royalties (as elected by Gilead in its sole discretion) that would otherwise be due to MacroGenics with respect to such Program DART or Licensed Product in such Calendar Year *** of the amount paid by Gilead or its applicable Affiliate or Sublicensee, as the case may be, to such Third Party with respect to such Program DART or Licensed Product in such Calendar Year (where any such amounts paid by Gilead or its applicable Affiliate or Sublicensee to such Third Party shall be equitably allocated among all products of Gilead or its applicable Affiliate or Sublicensee, as applicable, covered by such license or subject to such infringement); provided, however, that such deduction shall not reduce (A) the amount of milestones due to MacroGenics with respect to such Program DART or Licensed Product for such Calendar Year to less than *** of the amount of milestones that otherwise would have become due with respect to such Program DART or Licensed Product for such Calendar Year or (B) the royalty rate paid by Gilead in respect of Annual Net Sales of such Licensed Product in such Calendar Year to less than *** of Annual Net Sales of such Licensed Product in such Calendar Year, in each case ((A) and (B)) with any excess deduction carried over and applied to amounts due to MacroGenics with respect to such Program DART or Licensed Product in subsequent Calendar Years.

8.6 Healthcare Reform Tax. Notwithstanding anything herein to the contrary, for purposes of determining the sales milestones and royalties payable by Gilead under Sections 8.4 and 8.5, Gilead shall have the right to offset from Net Sales of Licensed Products sold in the United States that portion of the annual fee paid by Gilead and its Affiliates to the United States Government pursuant to Section 9008 of the Patient Protection and Affordable Care Act, Pub. L. No. 111-148 (as may be amended) reasonably attributable to Licensed Products, as determined in accordance with an equitable method as agreed in good faith by the Parties.

8.7 Reports; Payments. Within thirty (30) days after the end of each Calendar Quarter during which there are Net Sales or Net Receipts giving rise to a payment obligation under Section 8.4 or 8.5, Gilead shall submit to MacroGenics a report identifying for each Licensed Product, the Net Sales and/or Net Receipts for such Licensed Product for each country in the Gilead Territory for such Calendar Quarter, the calculation of royalties (including gross sales and all deductions taken from gross sales), and the royalties and the sales milestones payable to MacroGenics. Within fifteen (15) days of the delivery of each such report, Gilead shall pay to MacroGenics all royalties and sales milestones payable by it under Sections 8.4 and 8.5.

8.8 Methods of Payments. All payments due under this Agreement shall be paid in Dollars by wire transfer to a bank in the United States designated in writing by MacroGenics.

8.9 Late Payments. Any amount owed by Gilead to MacroGenics under this Agreement that is not paid on or before the date such payment is due as set forth herein shall bear interest at a rate per annum equal to the one month USD-LIBOR as quoted on Bloomberg (or if it no longer exists, a similarly authoritative source) plus *** calculated on a daily basis, or, if lower, the highest rate permitted by applicable Law.

*** = Portions of this exhibit have been omitted pursuant to a request for confidential treatment. An unredacted

8.10 Taxes. All payments due and payable under this Agreement will be made without any deduction, unless such deduction or withholding tax is required by applicable Laws. If the paying Party is so required to deduct or withhold, such Party shall (a) promptly notify the other Party of such requirement; (b) pay to the relevant authorities the full amount required to be deducted or withheld promptly upon the earlier of determining that such deduction or withholding is required or receiving notice that such amount has been assessed against the other Party; and (c) promptly forward to the other Party an official receipt (or certified copy), or other documentation reasonably acceptable to the other Party evidencing such payment to such authorities. Notwithstanding the foregoing, if as a result of (i) the assignment of this Agreement by Gilead to an Affiliate or a Third Party outside of the United States or (ii) the exercise by Gilead of its rights under this Agreement through an Affiliate or Third Party outside the United States, withholding tax in excess of the withholding tax amount that would have been payable in the absence of such assignment or exercise of rights becomes payable with respect to any amount due to MacroGenics under this Agreement, then Gilead shall pay to MacroGenics such additional amounts as are necessary so that MacroGenics receives the amounts that MacroGenics would have received if such payments were not subject to such withholding tax as a consequence of such assignment or exercise.

8.11 Books and Records; Audit Rights. Each Party (the “Audited Party”) shall keep (and, in the case of Gilead, shall cause its Affiliates and Sublicensees to keep) complete, true and accurate books and records in accordance with its Accounting Standards in sufficient detail for the other Party (the “Auditing Party”) (a) with respect to Gilead as the Audited Party, to determine the payments due and (b) with respect to MacroGenics as the Audited Party, to determine costs incurred in the conduct of Research activities under this Agreement. Each Auditing Party shall have the right, *** at its own expense, to have an independent, certified public accounting firm of nationally recognized standing, selected by the Auditing Party and reasonably acceptable to the Audited Party, review any such records of the Audited Party in the location(s) where such records are maintained by the Audited Party upon reasonable notice (which shall be no less than thirty (30) days prior notice) and during regular business hours and under obligations of confidence, for the sole purpose of verifying the accuracy of the amounts paid under this Agreement within a ***year period preceding the date of the request for review. The report of such accounting firm shall be limited to a certificate stating whether any report made or invoice or payment submitted by the Audited Party during such period is accurate or inaccurate and the actual amounts of Research costs and the amount of any Net Sales, milestone or royalty discrepancy. No other information shall be provided to the Auditing Party. The Audited Party shall receive a copy of each such report concurrently with receipt by the Auditing Party. Should such inspection lead to the discovery of a discrepancy to the Auditing Party’s detriment, the Audited Party shall pay the amount of the discrepancy within thirty (30) days after its receipt from the accounting firm of the certificate showing the amount of the discrepancy. The Auditing Party shall pay the full cost of the review unless the underpayment of milestones or royalties is greater than five percent (5%), or the overpayment of Research costs is greater than five percent (5%), of the amount due for the applicable period, in which case the Audited Party shall pay the reasonable costs charged by such accounting firm for such review.

by-Patent basis, share in such Out-of-Pocket Costs with each party’s percentage share determined by dividing (i) one, by (ii) one plus the number of Third Parties (if any) that is(are) required to reimburse MacroGenics for such Out-of-Pocket Costs. With respect to any Patent owned by Gilead or any Joint Patent that is being filed, prosecuted or maintained by MacroGenics pursuant to Section 9.3.1(a) in any country in the Gilead Territory, Gilead shall have the right, in its sole discretion, to assign such Patent in such country (or, in the case of a Joint Patent, to assign Gilead’s interest in such Joint Patent in such country) to MacroGenics or to cause the abandonment of such Patent in such country (only in the case of a Patent owned by Gilead), as MacroGenics may elect, and thereby to terminate Gilead’s obligation to reimburse such costs incurred thereafter, upon *** to MacroGenics.

(d) The Parties shall work together in good faith to agree upon a strategy for the prosecution of any Patents being prosecuted by MacroGenics pursuant to Section 9.3.1(a) in the Gilead Territory, including the list of countries in the Gilead Territory in which such Patents will be filed; provided, however, that (subject to Section 9.3.1(e)) MacroGenics shall have the final right to make such determinations. In addition, MacroGenics shall provide to Gilead such other information related to prosecution of any Patents being prosecuted by MacroGenics pursuant to Section 9.3.1(a) as Gilead may from time to time reasonably request to allow Gilead to track prosecution and maintenance of such Patents and shall consider in good faith any comments that Gilead may provide with respect to such matters.

9.4 Third Party Infringement.

9.4.1 Notice. Each Party shall promptly report in writing to the other Party any known or suspected (a) infringement of any of the MacroGenics Patents, Gilead Collaboration

*** = Portions of this exhibit have been omitted pursuant to a request for confidential treatment. An unredacted

version of this exhibit has been filed separately with the Commission.

Patents or Joint Patents; (b) unauthorized use or misappropriation of any of the MacroGenics Know-How, Gilead Collaboration Know-How or Know-How included in the Joint IP of which such Party becomes aware; or (c) notification under the Biologics Price Competition and Innovation Act of 2009, as amended, or similar law, from a biosimilar applicant arising from the filing of an application for the Regulatory Approval of a product intending to show that such product is biosimilar to any Licensed Product that is a reference product for which a claim of infringement of any of the MacroGenics Patents, Joint Patents or Gilead Collaboration Patents by the manufacture or sale of such product could reasonably be asserted, and shall provide the other Party with all available evidence regarding such known or suspected infringement or unauthorized use.

9.4.2 Enforcement Rights. Subject to the requirements and limitations of any MacroGenics Third Party Agreements with respect to the enforcement of Patents, including any rights of, and timeframes for, such Third Party licensors to comment on and review any filings or materials related thereto, the Parties agree:

(a) Gilead shall have (i) the sole right, but not the obligation, to initiate a lawsuit or take other reasonable action to enforce any Gilead Collaboration Patents that are Other Patents, in the Gilead Territory and (ii) the first right, but not the obligation, to initiate a lawsuit or take other reasonable action to enforce (t) any Gilead Collaboration Patents that are Product Patents, in the Gilead Territory, (u) any Gilead Collaboration Patents that are Platform Patents, with respect to Competitive Infringement in the Gilead Territory, (v) any Gilead Collaboration Patents that are Other Patents, in the MacroGenics Territory, (w) any MacroGenics Patents that are Product Patents, in the Gilead Territory, (x) any Joint Patents that are Product Patents, in the Gilead Territory, (y) any Joint Patents that are Platform Patents, with respect to Competitive Infringement in the Gilead Territory and (z) any Joint Patents that are Other Patents, in the Gilead Territory. Notwithstanding the foregoing sentence, Gilead shall not initiate any such lawsuit or take such other action with respect to any matter described in clause (ii) above without first consulting with MacroGenics and giving good faith consideration to any reasonable objection from MacroGenics regarding Gilead’s proposed course of action, and Gilead shall not initiate any such lawsuit or take such other action with respect to any matter described in clause (ii)(u) or (ii)(y) above without the prior written consent of MacroGenics, which MacroGenics may withhold in its sole discretion. MacroGenics shall cooperate in the prosecution of any suit under this Section 9.4.2(a) as may be reasonably requested by Gilead (including joining such suit as a plaintiff if Gilead is unable to initiate or prosecute such action solely in its own name); provided, however, that Gilead shall promptly reimburse all Out-of-Pocket Costs (including reasonable counsel fees and expenses) of MacroGenics in connection with such cooperation. In connection with any such proceeding, Gilead shall not enter into any settlement admitting the invalidity of, or otherwise impairing MacroGenics’ rights in, MacroGenics IP or Joint IP without the prior written consent of MacroGenics.

tangible personal property alleged or proven to result, directly or indirectly, from the possession, use or consumption of, or treatment with, a Program DART or Licensed Product Researched, Developed, Manufactured or Commercialized in the MacroGenics Territory for the applicable Licensed Program (or, as permitted under this Agreement, the Gilead Territory for the applicable Licensed Program), in each case by or on behalf of MacroGenics or its Affiliates or Sublicensees, including any product liability claims; (b) the Commercialization by or on behalf of MacroGenics or its Affiliates or Sublicensees of any Program DART or Licensed Product in the MacroGenics Territory, or the Manufacture of any Program DART or Licensed Product on behalf of MacroGenics by any Third Party pursuant to any consent or approval granted by Gilead under Section 3.2.5(e); (c) any actual or alleged infringement or unauthorized use or misappropriation of any Patent or other intellectual property right of a Third Party with respect to the activities of MacroGenics or its Affiliates or Sublicensees hereunder; (d) any breach by MacroGenics of its representations, warranties or covenants made under this Agreement; (e) any illegal or negligent act or omission or willful misconduct of MacroGenics or its Affiliates or Sublicenses or any of their employees, contractors or agents, in performing MacroGenics’ obligations or exercising MacroGenics’ rights under this Agreement; or (f) any exercise by MacroGenics of its rights under the license grant by Gilead in Section 4.2(d); provided, however, that the foregoing indemnity shall not apply to the extent that any such Losses are attributable to (i) an illegal act by or the gross negligence or willful misconduct of any Gilead Indemnitees, or (ii) are otherwise subject to an obligation by Gilead to indemnify the MacroGenics Indemnitees under Section 12.1, as to which Losses the provisions of Section 12.4 shall apply.

12.3 Procedure.

12.3.1 In the event of a claim by a Third Party against any Person entitled to indemnification under this Agreement, the Party claiming indemnification (in such capacity, the “Indemnified Party”) shall promptly notify the other Party (in such capacity, the “Indemnifying Party”) in writing of the claim (it being understood that the failure by the Indemnified Party to give prompt notice of a Third Party claim as provided in this Section 12.3 shall not relieve the Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that such Indemnifying Party is actually prejudiced as a result of such failure to give prompt notice). Within thirty (30) days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, undertake and solely manage and control, at its sole expense and with counsel reasonably satisfactory to the Indemnified Party, the defense of the claim; provided, however, that if MacroGenics is the Indemnifying Party and the claim relates to a Program DART or Licensed Product with respect to which a Phase 2 Clinical Trial has been Completed, then Gilead may, at any time upon written notice to MacroGenics, assume sole management and control of the defense of the claim, at its sole expense (provided, however, that Gilead shall not be required to reimburse MacroGenics for any expenses incurred by MacroGenics in connection with MacroGenics’ defense of the claim prior to such assumption). If the Indemnifying Party does not undertake such defense in accordance with the preceding sentence, the Indemnified Party shall control such defense. The Party not controlling such defense shall cooperate with the other Party and may, at its option and expense, participate in such defense with counsel of its choice; provided, however, that if the Indemnifying Party assumes control of such defense as set forth above and the Indemnified Party in good faith concludes, based on advice from counsel, that the Indemnifying Party and the

*** = Portions of this exhibit have been omitted pursuant to a request for confidential treatment. An unredacted

version of this exhibit has been filed separately with the Commission.

Indemnified Party (or the relevant MacroGenics Indemnitee or Gilead Indemnitee seeking indemnification) have conflicting interests with respect to such action, suit, proceeding or claim, the Indemnified Party’s counsel may fully participate in such defense and the Indemnifying Party shall be responsible for the reasonable fees and expenses of one counsel to the indemnified Persons solely in connection therewith. The Party controlling such defense shall keep the other Party advised of the status of such action, suit, proceeding or claim and the defense thereof, shall provide the other Party copies of material documents and filings related to such action, suit, proceeding or claim and shall consider recommendations made by the other Party with respect thereto. Except if the Indemnifying Party did not undertake defense of the claim as set forth above, or if the Indemnifying Party and the Indemnified Party (or the relevant MacroGenics Indemnitee or Gilead Indemnitee seeking indemnification) have conflicting interests with respect to such action, suit, proceeding or claim and the Indemnified Party engages separate counsel, as provided above, the Indemnifying Party shall not be liable for any litigation costs or expenses incurred by the Indemnified Party without the Indemnifying Party’s written consent. The Indemnified Party shall not settle any such action, suit, proceeding or claim without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld, delayed or conditioned. The Indemnifying Party shall not settle, without the prior written consent of the Indemnified Party, any such action, suit, proceeding or claim, or consent to any judgment in respect thereof, that does not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto, that imposes any liability or obligation on the Indemnified Party or that acknowledges fault by the Indemnified Party.

12.3.2 Notwithstanding anything to the contrary above, in the event of any claim or criminal action brought by a Governmental Authority against a Gilead Indemnitee for which indemnification may be sought under this Section 12.3, Gilead shall have the right to control the defense, litigation, settlement, appeal or other disposition of the claim or action at MacroGenics’ expense.

12.4 Allocation. In the event a claim falls within the scope of the indemnity given by each Party in Section 12.1 or 12.2, as the case may be, any payments in connection with such claim shall be apportioned between the Parties in accordance with the degree of fault attributable to each Party.

12.5 EXCLUSION OF CONSEQUENTIAL DAMAGES. EXCEPT WITH RESPECT TO A BREACH OF SECTION 4.9, ARTICLE 10 OR THIRD PARTY CLAIMS THAT ARE SUBJECT TO INDEMNIFICATION UNDER THIS ARTICLE 12, NEITHER MACROGENICS NOR GILEAD, NOR ANY OF THEIR RESPECTIVE AFFILIATES, WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR PUNITIVE DAMAGES, WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY OR CONTRIBUTION, AND IRRESPECTIVE OF WHETHER SUCH PARTY OR ANY REPRESENTATIVE OF SUCH PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE.

Press Release

MacroGenics and Gilead Sciences Enter Strategic Alliance to Develop and Commercialize Four DART^™ Products

•

Based on MacroGenics’ proprietary DART technology for generating bi-specific antibodies

•

Gilead receives rights to four pre-clinical programs

•

MacroGenics retains development and commercial rights to one of the programs in major markets outside North America and the European Union

ROCKVILLE, Maryland – January 7, 2013 – MacroGenics, Inc., a privately held biotechnology company that develops next generation antibody therapeutics, announced it has entered into a license agreement with Gilead Sciences, Inc. (Nasdaq: GILD) for the development and commercialization of Dual-Affinity Re-Targeting (DART^™) products directed at up to four undisclosed targets. MacroGenics’ DART technology is a proprietary, bi-specific antibody platform in which a single recombinant molecule is able to target two different antigens.

“We look forward to building a long-term collaboration with MacroGenics, a leader in the development of bi-specific antibodies, which represents a promising new area of research,” said ▇▇▇ ▇. ▇▇▇▇▇▇, M.D., Ph.D., Senior Vice President, Oncology and Inflammation Therapeutics at Gilead. “This partnership underscores Gilead’s commitment to developing innovative therapies that address significant unmet medical needs for patients with cancer and other life-threatening diseases.”

Under the terms of the agreement, MacroGenics could receive a total of up to $30 million in license fee payments, and up to an additional $85 million in pre-clinical milestones across the four DART programs. Gilead has exclusive worldwide rights for three of the programs. For one program, MacroGenics retains development and commercialization rights outside of North America, Europe, Australia and New Zealand, which encompasses multiple major markets including Japan, China, Korea, Brazil, Russia and others. Gilead will fully fund MacroGenics’ research activities with respect to the four programs. MacroGenics could also receive up to approximately $1 billion in clinical, regulatory and commercialization milestone payments if all four programs achieve the requisite milestones. Finally, MacroGenics may receive tiered (up to low double-digit) royalties on future net sales.

“We are very pleased to enter this collaboration with Gilead, a world-class biopharmaceutical company committed to the development of innovative therapeutics,” said ▇▇▇▇▇ ▇▇▇▇▇▇, M.D., Ph.D., President and CEO of MacroGenics. “As the fourth major collaboration around our DART platform in the past two years, this deal represents the latest validation of our ongoing efforts.”

About DARTs

MacroGenics’ DART technology enables the generation of highly stable antibody-based therapeutics that can simultaneously target two different antigens. DART therapeutics can accommodate virtually any variable region sequence in a “plug-and-play” fashion, are highly potent, and have very favorable manufacturing properties. DARTs may be engineered with either short or extended serum half-life to support various applications in different disease areas. In one particular configuration, DART proteins can be used to redirect the body’s cell-destroying, immune effector cells against tumor cells. To date, the company has engineered over 100 different DART proteins developed for both internal pipeline programs and external collaborators. MacroGenics anticipates submitting an IND for its first DART product candidate in late 2013. MacroGenics continues to expand its significant patent estate around its DART technology.
